Topic: Wounded in battle (Read 49395 times)

I thought it might be fun to have a topic on SoR where we can brag about our foolishness.Feel free to post some pics here showing injuries you've gotten from working on your robotics projects. Solder-burns, laser-scars, Lithium explosion damage, ... Show it to the people! You may also show damage to your robots caused by crashes, burns, torpedo's, etc.

Infact just show anything or anyone that got hurt by robotics.

In my defense: this is to warn people about the dangers of robots and building them.

Ahh yes ! The legendary first voltage regulator (or was it a FET for the motor driver?)

I wish I had taken a pic of my finger when I burnt it a few months ago while soldering.I wasn't looking, and i wanted to grab the soldering iron fast, but I grabbed a bit too far and I completely grabbed the iron part... Needless too say my hand didn't feel so good for the next days

Some parts of my skin looked like cooked chicken...mmm chicken...but don't worry, I didn't hold it for very long. I released it and while pulling my arm away very fast, I bumped my elbow to the arm of the guy next to me...pretty hard

In my schools robotics club I managed to get a nice looking scar to match my other(the new one's pink part is an inch long and 1/8 inch thick) there were no bandages so I used duct tape and paper towels to clean it up, and the cut was made of an oily igus rod from BEST. It happened from my hurry and not wanting to look when i literally jumped onto the ground to unplug the battery.

Im not safe

I was testing some salvaged DC motors with a friend and hooked them up to a power supply. I forgot and didn't notice that he had switched the adjustment dial to control amperage instead of voltage. So I started turning the dial, thinking I was adjusting voltage to test how fast the motor would go and the motor speed barely increased. I kept turning the dial slowly, thinking "hmmmm this is strange". That's when I saw it was on amperage and just as I started to turn the dial back...

BAAAMMMMMMMMMMMM!

The capacitor wired to the power/ground connectors of the motor BLEW UP. There was cotton/confetti stuff all over the lab table. Luckily neither of us was hit by flying shrapnel, but my ears hurt for a few hours after that. Moral of the story? Check and double check the display!

oooww, electolytic capacitors really stink if you blow them up. The whole room stinks like rotten fish and there's that cotton stuff everwhere

So far I only had one serious burn from the soldering gun... My soldering gun is at my left hand, but despite being a lefty, I used some things better with my right hand... So when I changed hand... I also needed to change skin... I almost grabbed the soldering tip!!!It was a really bad burn bad there but I had to overcome it because I had volleyball training that day (and when you are in a crush with a girl you can't miss - well it didn't turn out well but there are more to come !!! so I'm nice)(and yeah my finger was bad - but it was right hand so never mind!!!)Some cuts... regular thing... And with a big hope not to have respiratory problem after this long hours of soldering in a not so well ventilated environment....

For whom the interrupts toll...

P.S. I've been inactive for almost a year... Don't give promises but I'll try to complete my tutorials. I'll let you know when..

The #1 lesson I learned: Always be afraid of anything that is potentially dangerous, even if you are an expert at it. As soon as you lose the fear, you make dumb decisions.

My list of pain:Almost cut my thumb off with a bandsaw . . .Burning my finger with a mosfet, as ed pointed out aboveSeveral near misses of highspeed flying parts hitting close to my eyesPoorly secured parts in a drill press spinning and hitting me

List of pain from my friends:Electrocution, several times . . .Almost cutting various fingers off with a bandsaw, needing stitches(I remember following a trail of blood to find my friend)Capacitors exploding in the face (mostly smoke and noise)Exploding L298 motor driver (pretty colors!!!)Battery acid burns (resulted in him taking his pants off)Long metal fragment passing through a thumb (through the fingernail, too)Sulfuric acid spill (resulted in him stripping to his boxers)

Tips:Wear safety goggles - always. I wear them when I solder, cut leads off of boards, machine, use chemicals, even when I turn on a new circuit for the first time. You only have two eyes.

When using chemicals, do it outside or in a very ventilated area. I also vent my solder fumes (lead poisoning!). Read the safety manuals before using the chemical.

Tie down flammables and store in cool safe locations.

Read the manual for your power tools before using them. No loose clothing. Make sure you always have someone close by if something goes horribly wrong. People cutting off fingers is actually fairly common with power tools . . .

This didn't happen to me, but i once heard about a guy who cut his finger off with a circular saw.

What happened was the lights in the room were powered by 50Hz AC electricity and the saw must have been rotating at a multiple of 50 revolutions per second. This caused the strobe effect where the saw looked stationary. The guy thought, thats weird... it sounds like its on... so he touched it and chopped his finger off!

You best note this with TV's and TFT's in the dark... I've never noticed this with regular lamps... Must have been the tube lamps we have at bathrooms!!! Poor guy though...

Was soldering and drop the iron, I was worried about catching the carpet on fire and it hit my bare leg. The bad part was it stuck to my leg and I had to rip it and several layers of skin off. So don't weed whack or solder in shorts

1- spilled batery acid over myself and didnt know about it till i got to wally world and saw bunch of holes in my pants (wearing them now )2- inhaled ALOT of toxic fumes (pretty much anything you can think off)3- the generic burns/cuts\

Ive cut myself pretty badly once or twice, soldered my fingers several times, impaled my fingers with ICs (once had an entire 555 stick completely into my friggen index finger... Then my nose started flashing on and off, dunno what that was about.

I was in my schools physics lab with my physics teacher attempting to figure out the thurst of a outrunner motor with a 5 inch computer fan. He supposedly clamped it, told me to put it on full power, as soon as I did it shot off the clamp hit the table and two blades shot behind my head, another shot into his computer, and the other two were never found.

Before we give them the slightest technology they are killing are brains with fumes, drawing our blood with tools, burning us, becoming suicide bombers, attempting to commit suicide thus causing us to try and fly to their aid most commonly resulting in an injury to us, and becoming very confusing very fast.

now what will happen when they can actually think....
